The Chandra X-ray Observatory (CXO), launched by NASA on July 23, 1999, is a flagship-class space telescope. Chandra X-rays captured many stunning images of cosmic phenomena over its two decades of work.And the most iconic supernova remnant of these is Cassopia a. Located at a distance of about 11,000 light years from our Earth, is A, such as a shining debris field after a massive star burst, called A. When a star's fuel runs out, it collapses on its own, and is known as a supernova.It is seen as one of the brightest objects in the universe. The same astronomers believe that the supernova explosion occurred around the year 1680. Launched on August 26, 1999, the Chandra X-ray detected several images, near the center of a complex pattern of debris spreading from a broken star, and for the first time a dense object called a neutron star, it called a supernova Also left behind.The data from the Hubble Space Telescope have been combined with th...
